    Reland "[turbofan] add value input to DeadValue" · 6328c565
    Tobias Tebbi authored
    DeadValue was a constant node of type None. This is unsound in the
    presence of re-scheduling. This CL adds a value input to DeadValue,
    which preserves the dependency on the original node of type None.
    
    This reland addresses the bug that the EffectControlLinearizer could destroy dependencies of DeadValue by attaching DeadValue nodes to the effect chain in the EffectControlLinearizer.
